' Specification of Letters Patent.

Patented June .26, 191?.

Application filed September 30, 1913. Serial No. 792,623.

To all whom it may concern:

Be it known that I, WALTER SHAW, a citizen of the United States,residing at Dedham, in the county of Norfolk and State of Massachusetts,have invented certain Improvements in Machines for Setting Fasteners, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figure This invention relates tomachines for setting fasteners, such as gromets, eyelets, lacing studs,etc., in sheet material and is shown herein as embodied in a machine forsetting gromets and Washers in textile goods, although many of itsfeatures have a more general application.

It is an object of-the invention to provide a machine having automaticmechanism for presenting a gromet to one setting die and a washer to theother so that the operator has only to present the work and start themachine in order that the barrel of the gromet may be passed through thehole in the washer and clenched upon its outer surface. In themanufacture of sails, hammocks, and similar goods such a machine is ofgreat assistance.

An important feature of the invention consists broadly in settingdevices which are arranged to move to and from stationary raceways insupplying themselves with the requisite fastener parts. Many advantagesresult from this construction. In the first place, in the machine thepoint of presentation of the work is left entirely unobstructed andthere is no danger that either the work or the operators hands will beharmed, as might result if raceways were moved intermittently into thespace between the sets; then, the upper die may be arranged to occupy aninitial position out of line with the lower die, and the presentation ofthe work still further facilitated by affording the operator anunobstructed view of the lower die upon which it is customary to locatethe work; further, the lower die may be arranged to occupy its settingposition initially so that the work may be held at rest during thesetting operation; and still further, the construction and mounting ofthe raceways may be simplified and the whole operation of the machinerendered more positive and more quiet than heretofore,

The employment of stationary raceways is of particular importance in amachine for handling gromets and washers as the quantity of thesearticles necessary to supply the machine for any length of time amountsto very considerable weight and the raceways to accommodate them arelarge and heavy. The operation of the machine at a high speed is,therefore, very greatly facilitated by making the raceways stationary.It is believed that heretofore no machine of this type has been put intopractical operation.

In the machine herein disclosed the gr0mets are supplied by the upperraceway and set by an inverted die. In this connection another featureof the present invention consists in arranging the die to move fromreceiving position at the raceway end to setting position above the workmore quickly than the gromet will fall under the influence of gravity.The construction of the upper die is thus simplified and the necessityfor a retaining spring or other device for such purpose is obviated.

Other important features of the invention reside in the mechanicalconstruction of the various elements and in their cooperativearrangement whereby the operations above outlined are rendered possibleor improved in their character.

These and other features of the invention will be best understood andappreciated from the following description of a preferred embodimentthereof selected for the purposes of illustration and shown in theaccompanying drawings in which' Figure 1 is a view of the machine inside elevation.

Fig. 2 is a view of the machine in front elevation.

Fig. 3 is a side view of the machine partly in section.

Figs. 4 and 5 are views in perspective illustrating parts of the lowerraceway and setting die.

Figs. 6 and 7 show the setting dies in two different positions occupiedby them in a cycle of the machine.

Fi 8 is a sectional view showing the position of the setting dies in thesetting operation.

Fig. 9 shows the'setting dies in one of their intermediate positions.

Figs. 10 and 11 illustrate the separate parts of the upper and lowersetting dies with their mountings.

Themachine frame 2 is so shaped as to carry the setting dies on an angleof about 45, an arrangement which facilitates the presentation of workto the machine. The

frame 2 is provided with bearings for the main shaft 4 whlch carrles atone end a hand wheel 5, and at the other end a driv pair of cam disks 8and 10, one being lo-.

cated adjacent to either side of the frame. In the faces of these camdisks are formed cam grooves by which the various instrumentalities ofthe machine are actuated.

In the upper portion of the frame 2 provided a guideway for areciprocating head 12, a face plate 13 secured to the frame covering theupper portion of the head.

The head is reciprocated by the toggle links 14 and 16 which areconnected to the link 18'. The link 18 is slotted at its rear end tostraddle the main shaft 4, which thus acts as a guide for the link, andis provided with a cam roller 19 arranged to run in the cam groove 20formed in the inner face of the cam disk 10.

At its lower end the head 12 is provided with transverse guide-ways 11in which is mounted a sliding plate or carrier 22 for the upper settingdie. The carrier 22 is re-' ciprocated transversely in order to move thesetting die 30 back and forth between its setting position, which is inline with the axis of head 12, and the delivery end of the stationaryraceway 90 by which this setting die is supplied with gromets. At itsrear end the carrier 22 is pivotally connected to a link 24 slotted toreceive the shaft 4 similarly to the link 18 and carrying the cam roller26 which runs in the cam groove 27 formed in the inner face of the camdisk 6. The cam grooves 27 and 20 are so shaped as to impart the properlateral and longitudinal movements to the setting die 30 as will beexplained hereinafter.

The construction of the upper setting die 30 will be clear from Figs. 8and 10 of the drawings. This die is shaped to receive :1 gromet and isprovided with a center spindle 32 of such diameter as to center thegromet through which it is passed. The carrier 22 is provided with athreaded boss for the reception of a threaded adjustable bearing piece38. The position of this piece 38 in the carrier determines thelongitudinal position of the upper setting die 30. Loosely receivedwithin the bearing piece 38 is a split clamping member 36 having at itslower end a beveled flange. Within the clamping member 36 is receivedthe shank of the setting die 30. A threaded cap 34 is screwed upon theboss of the carrier 22, and 15 provided with a beveled annular surfacewhich contracts the split clamping memberinto setting position. Theplunger 44 hasan end of reduced diameter and is normally held by thespring 46 in such position that its surface is flush with the innersurface of the guideway 11. The upper end of the bore in which theplunger 44 and its spring are received is closed by a screw plug 48which permits convenient access to these parts of the machine ifnecessary. It will be understood that the spring 46 is of sufficientstrength to hold the upper end of the spindle 32 normally within thecarrier 22 so that there will e no interference with the transversemovement of the carrier. A small spring 42 encircles the upper end ofthe spindle 32 and serves to keep the spindle from dropping down whileit is being moved to and from the raceway. In this movement the upperend of the spindle slides upon the face of the guideway 13 in the head12.

In the lower portion of the frame 2 there is provided a guideway for thereciprocating head 50, which at its upper end is provided with atransverse guideway for the side plate or carrier 64 of the lower die70. The head 50 is moved up and down by the toggle links 52 and 54connected through the link 56 to a cam lever 58. The cam lever 58 ispivoted upon a transverse pin 60 and its upper end carries a cam roller61 arranged to run in a cam groove 62 formed in the outer face of thecam disk 6- The carrier 64 is moved transversely to carry the settingdie 70 back and forth between its setting position in line with the axisof the head 50 and the delivery end of the stationary raceway 110 bywhich it is supplied with washers. For this purpose the carrier 64 ispivotally connected at its rear end to a link 66 which in turn isconnected to the lower end of a cam lever 67 also mounted on the pin 60.At its upper end the lever 67 is provided with a cam roller which runsin a cam groove 68 formed in the inner face of the cam disk 10. Thelower die 70 is provided with a shank which is received within a splitclamping member 72. which rests upon an adjustable threaded bearingpiece 71. The bearing piece 71 is threaded on a sleeve 7 6 which isslidingly mounted'in a bore formed in the lower end of the carrier 64.Surrounding the sleeve 76 is a sleeve 84 of such diameter that it willslide freely upon the enlarged head of the die 70. This sleeve isnormally held in its upper position by a spring 85 and is prevented frombeing ejected by a screw projecting through a part of the carrier 64into a slot in the side of the sleeve 6 shown in Fig. 8. Movementbetween the sleeve 84 and the sleeve 76 is limited by a pin set in theside of the sleeve 76 and projecting into a slot in the sleeve 85, asshown in Figs. 8 and 11.

The lower setting die and its associated parts are yieldingly backed upduring the setting operation by a plug 7 8 arrange in a bore in theupper part of the head 50;

The plug is arranged to slide upon a pin 80 set in the head 50 of thebottom of the.

bore and is normally retained with its surface fiush with the surfaceguideway in the head 50 by a stiff compression spring 82. It will beseen that at all times except during the setting operation, the lowersurface of the sleeve 76 will be maintained in the same plane as thebottom of the carrier 64 so that transverse movement of the latter willnot be obstructed in any way.

When the upper end of the spindle 32, or the lower end of the sleeve 7 6have been displaced sufiiciently to enter the recesses in the respectiveheads which carry them the carriers 22 and 64 will be positively lockedagainst transverse movement and there will be no danger of throwing thedies out of alinement even should the material hang heavy on the lowerdie or should other disturbing influence exist.

The upper raceway 90 by which the gromets are supplied is secured to theframe 2 in stationary but adjustable position by means of the screws 92and 93 which are threaded through the sides of the frame as shown inFig. 1. rearwardly for some distance in a direction parallel to themovement of the carrier 22 and then curves upwardly to a point above theframe where it carries a hopper 94 in which the gromets are placed. Thehopper,

94 communicates with the raceway 90 through one or more parts of theusual construction and the gromets are caused to pass through such partsby a brush or similar agitator driven by a pulley 96 beneath the hopper.The pulley 96 is-connected by the belt 98 with an intermediate pulley102 on the transverse shaft 100 journaled in bearings formed in theframe 2. Through the belt 103 the pulley 102 is connected to anotherpulley 104 connected to a larger pulley 106 which runs freely on theshaft 4. The pulley 106 is driven by a belt 107 from a counter shaft orthe like and is operated independently of the main driving connectionThe raceway 90 extends,

to the machine so that the agitators in the hoppers may be rotated andthe raceways filled with gromets and washers before the machine is setin operation or during the intermissions between setting operations.

It will be seen that the gromets are delivered from the hopper 94 withtheir barrels uppermost and that as they pass down the curved raceway 90they are reversed so that the die 30 eventually picks each gromet fromthe raceway with its barrel projecting downwardly. A detent of the usualconstruction is located at the delivery end of the raceway 90 to preventthe gromets from running out of the raceway under the influence ofgravity.

The lower raceway 110 which supplies washers to the die 70 extends in astraight line from its delivery end on washer hopper 114 and is securedto the frame in stationary but adjustable position by the screws 111 and112 as shown in Fig. 1. The hopper 114 communicates withi the raceway110 through the usual parts and is provided with. a brush or agitatordriven by I ulley 115. The latter is connected by a be t 116 to a smallpulley turning with the larger pulley 106 above referred to, so that theagitators of both hoppers are both driven through independently of themachine and through the belt 107 as already explained.

Adjacent to its lower end the raceway 110 is provided with a pivoteddetent 118 which normally retains the washers in the raceway but permitsthe endmost one to be picked off by the lower die 70.

It is desirable to locate the washer on the die 70 concentrically andspaced from the central projecting portion of the die in order that thegromet barrel may pass through the washer and be clenched properly uponits lower surface. One purpose of the sleeve 84 is to insure the correctlocation of the washer as it is drawn out of the raceway. When the head50 is elevated with the die 7 O beneath the raceway 110, in order topassthe die 70 through the lowermost washer, the sleeve 84 encountersthe lower side of the raceway and yields downwardly as shown in Fig. 9.hen the carrier 84 is subsequently moved toward the front with the die70 engaging the washer, the sleeve 84, as soon as it is carried beyondthe end of the raceway, is elevated to its normal position and locatesthe washer by engaging its rim. In order that the movement of the sleeve84 may not be so abrupt as to displace the washer, the upper edge of thesleeve is beveled at its rear side and this insures a gradual movementof the sleeve 84 when it is permitted to rise.

The various cams are so shaped and the clutch mechanism so designed asto bring the machine to rest with its parts in the positions shown inFigs. 3 and 6, The carrier 22'for the upper die 30 occupies its rearmostposition in which the die 30 is in line with the endmost gromet in theraceway 90 and the head 12 occupies its uppermost position. The lowerdie 70 occupies its setting position and has been supplied with awasher. The movement of the die 70 by which the washer is supplied takesplace immediately after each setting operation and before the machinecomes to rest. In the stopped position of the machine, therefore, thedie 70 is provided with a washer.

In the normal operation of the machine the work is punched and threadedupon the die 70, as shown in Fig. 3, the Washer being beneath thepunched hole. The machine is then started by depressing the treadle rod7 and the head 12 is immediately lowered .sufliciently to cause thespindle 32 of the die 30 to pass into the barrel of the endmost grometin the raceway 90. The carrier 22 is thereupon advanced forwardly to itssetting position as indicated by the dotted path in Fig. 6, being alsomoved toward the work by the further depression of the head 12 as soonas the die 30 has cleared the end of the raceway. In F ig. 7 the partsare shown head 50 elevated, carrying the parts into the position shownin Fig. 9. Finally, the carrier 64: is returned to its forward position,the head 50 moved to its upper position and the machine stopped.

When the endmost gromet has been'drawn out of the upper raceway it wouldnaturally be free to fall, but the movement of the setting die 30 ismuch faster than the movement of the gromet which would be produced bygravity and'the result is that the gromet remains in place upon the dieby reason of its inertia.
